ATTACHIVIEN '1 FOR ADDING-MACHINES.

To all whom it may concern:

Be it known that I, OLIVER L. RnrsER, a citizen of the United States, residing at C0- lumbus, in the county of Franklin and State of Ohio, have invented new and useful Improvements in Attachments for Adding-Machines, of which the following is a speclfication.

This invention relates to attachments for adding machines, and more particularlyto means for operatlng the arm connected with the main or actuating shaft, said arm being thrown to operative position by means of a foot lever or pedal.

One object is to provide a device which may readily be attached to a machine of an ordinary commercial type and which shall comprise a bracket or the like pivotally mounted, a foot lever, a rod connecting the foot lever with the bracket, but being detachable with reference thereto, and means for throwing the rod out of engagement automatically, permitting the hand operated member of the machine toreturn to normal position without taking the foot fromthe edal. p With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of elements hereinafter described and claimed.

In the drawings- Figure 1 is a view of the attachment in side elevation as applied to a machine, the latter being shown in outline, together with the stand.

Fig. 2 is a front elevation of the structure'- of Fig. 1.

Figs. 3 to 5 are perspective views, showing,

for the rod.

The frame or casing of a machineof usual commercial type is designated 10 and the stand therefor is shown at 12, the actuatin rock shaft being designated 13, and the usua the stud and bracket and'meansfor auto- Imatically throwing the rod out of engagelever operated by hand for oontrollingthe shaft 13 being designated 14;. o

bracket 15 comprising a downwardly extend ing member 16 and a. horizontally extendin member 17 projecting at an acute angle wit member 16. The member 16 is provided with an aperture 18 permitting of the proper ries a stud or the like designated 20 .with' which the hook 21 of the rod 22 cooperates Specification of Letters Patent.

Serial No. 236,618.

for the purpose of actuating the bracket and thereby moving the usual arm 14: for the customary purpose, that is for recording totals and the like. Clampin means 24 are provided at the end of arm 1? permitting of the positive engagement thereof with arm 14.

The rOd 22 is pivotally connected at 26 with lever or pedal 27 operated by foot power, and this rod 22 is-returned to normal position when the foot is withdrawn from the pedal, by means of a spring 28. If the foot is withdrawn in the manner indicated the arm 14 will return to normal position owing to the action of the spring .within the machlne, controlling said arm. If it is desired to retain the foot on the pedal, the machine may be operated in that manner by employing means for throwing off the hook 3 v member 21, placing it out of engagement with stud 20. For this purpose I provide rod 22 with an offset portion 32 cooperating with a wheel 33 mounted in a bracket 34 supported by any suitable clamping device such as-that shownat 35. The 0 set portion 32 is'opposite. thewheel and between the .latter'and the frame when the hook 21 is out of engagement, and is thrown to that pothe necessity for employing other power J I enable amount of time is also saved, since thev operated mechanism is avoided. An appreoperator does not have to move. his hand" handle 14. What is claimed is:

1. In adevice of he class described, the

back and forth between the work andthe I A i combination with the operating arm of an adding machine or the. like, of a bracket securedtlieretoand moving therewith, a stud carriedbythe bracket, a pivotally mounted foot -'.1ev'er, a'rod connecting the lever with ment with the stud and bracket.

2 Ina device of the class described, the combination with the actuating shaft of an Ladding machine or the like, and an actuating arm carried by said shaft, of a bracket operating with said arm, a stud carried by the bracket, a foot lever, a rod connected with the foot lever and detachably connected with the stud and bracket, means for returning the rod and foot lever to normal position when the foot lever is released, and means for automatically throwing the rod out of engagement with the stud and bracket without removing the foot from the lever.

3. In a device of the class described, the combination with the actuating shaft and actuating arm of an adding machine or the like, of a bracket moving with said arm, a pivotally mounted foot lever, a rod pivotally connected with the foot lever and detachably connected .with the stud and bracket,

and means for automatically throwing the rod out of engagement with the stud and bracket, said means last named including an ofi'set member carried by the rod, and means mounted on a stationary element and engaged by the offset member ata predetermined point in the effective movement of the rod and the actuating arm and shaft of the 20 machine.
